SASH-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 263,240, dated August22, 1882. Application filed December 21, 1881. (No model.)

To all whom it may concern Be it known that I, FRANK P. STONE, ofChicago, in the county of Cook and State of Illinois, have invented anImproved Anti-Rattling Sash-Spring, of which the following is aspecification. I

In the accompanying drawings, illustrating my invention, Figure l isperspective view of a window sash and frame with my springs applied.Figs. 2 and 3 are elevations of my springs. Fig. 4 is a group showing ablank and a spring formed from it, and Fig. 5 is another group showing ablank and a spring formed from it.

It will be obvious from Figs. 2,3, 4, and 5 how the springs are formedwithout further description.

The object of my invention is to prevent the noisy rattling of thewindow sash of .cars, coaches, or dwellings, due to bad fitting and windor motion.

To accomplish this object[ construct a triple spring, A, of any suitablespring metal, to be capableof some modifications of form. For

example, all three of the spring parts may stances two of these triplesprings having.

the form in which only one end of the springs is secured together, asshown in Figs. 1 and 4, may be applied near the middle of the sash andanswer very well. When I form triple springs of this latter kindconnected only at one end I may form them of a single piece of metalslitted in two places and folded at the base, as illustrated in Fig.4.Should inferior spring metal be employed in the manufacture of thesetriple springs, elastic pads or cushions E, of rubber or any othersuitable material, may be placed underneath the springs to aid theirresilient action.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The triple anti -rattling sash spring above described, composed of threecurved springs combined, one to rest upon the edge and one upon eitherface of the sash, as set forth.
